Modified-Chinese-chestnut-protein-coated slow-release fertilizer special for hawthorn fruits

Abstract

The invention discloses a modified-Chinese-chestnut-protein-coated slow-release fertilizer special for hawthorn fruits. The fertilizer is made from the raw materials, by weight part, 34-35 of coarse powder of peanut shells, 2.3-2.5 of sodium carboxymethyl starch, 15-16 of sugarcane ash, 3-4 of ammonium polyphosphate, 1.1-1.3 of cobalt sulfate, 4-5 of ammonium chloride, 2-3 of tamarind seed polysaccharide gum, 76-80 of fresh Chinese chestnuts, 18-22 of fruits of ficus pumila, 1.2-1.4 of a glutamine transaminase preparation and a proper amount of water. The fertilizer can be stable in a plough layer of soil for a long time, has adhesion and graininess for improving soil permeability, and improve the water retention ability of the soil. Continuous release of nutrients meets nutrient requirements of hawthorn fruit trees. Acid raw materials, such as ammonium chloride, are used and match organic matters, such as sugarcane ash and coarse powder of peanut shells, for enabling the soil to change into weak acid soil, which is suitable for the hawthorn fruit trees to grow and to be cultured.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a modified chestnut protein-coated slow-release fertilizer specially used for hawthorn. Background technique [0002] With the development of specialization, industrialization and scale of agricultural production in my country, the requirements of agriculture for fertilizer and soil fertility are constantly upgrading, while traditional fertilizers have restricted the sustainable development of agricultural planting due to their low nutrient utilization. The application of coated slow-release fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated slow-release fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the function of the coating material is single, usually only slow The controlled-rele...

Problems solved by technology

However, at present, the coating materials of common coated slow-release fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the function of the coating material is single, usually only slow The controlled release effect does not take into account the effects of water absorption, antibacterial, antioxidation, etc., and the practicability for different soil environments
